Description

  The present invention relates to a snack food for pets. More specifically, the present invention relates to a snack food suitable for serving as a “snack” supplementary food as well as a human snack food for dogs as well as domestic pets such as cats and ferrets. .

  In recent years, pets such as dogs and cats kept at home have also developed obesity, hyperlipidemia, diabetes, etc. due to lack of exercise, increased stress, and excessive intake of nutrients, as in humans. Tend to increase. In particular, the number of pets falling into a metabolic syndrome state in which various diseases are likely to be caused by visceral fat obesity has been steadily increasing recently, and there is a strong demand for preventive measures including the treatment.

  On the other hand, pets have an excellent “healing” effect through human contact, contributing to stress relief and mental stability, and contact exchanges with pets have been used as part of medical practices in hospitals and nursing homes recently. There has been a lot to be done.

  However, as the number of opportunities for humans to interact with pets increases, humans are encouraged to add their favorite food and supplements to their pets as the most effective means of bringing them closer to themselves and deepening their bonds. As a result, pets are often over-nutritioned.

As foods or supplementary foods provided as such snack foods, various foods as shown in the following Patent Documents 1 to 4 have been used.
Japanese Patent Application Laid-Open No. 7-1515917 JP-A-6-153810 JP 2002-233313 A JP 2004-89010 A

  However, when the food for breeding as described in Patent Documents 1 and 2 is frequently provided as a snack food separately from the regular feeding, it becomes a factor causing metabolic syndrome due to overnutrition to the pet. On the other hand, as shown in Patent Documents 3 and 4, when providing supplementary foods such as “pacifier” or “chewing gum” for dogs and cats as a luxury chewing tool, Although there is little risk of over-nutrition as described above, as a means to deepen interaction with and contact with pets, humans are less likely to repeatedly act and act to give pets the food they prefer. As a result, there was a dilemma in which the satisfaction on the side was poor, and as a result, the above-mentioned “healing effect” could not be sufficiently expected. In addition, in the case of pets raised indoors, if the above-mentioned chewing tool is provided, there is a problem that indoor furniture and the floor are soiled due to dripping and dripping a large amount of saliva.

  The present invention is a pet that can be suitably used as a reward for training, or as a supplement that is given as a “snack” to the pet, in addition to the regular feeding for rearing the animal, under the background circumstances described above. The purpose is to provide a snack food.

  More specifically, even when given in a considerably large amount, it is undernutrition, has a low risk of causing health problems to pets, and, of course, given to a donating human being by giving a large amount repeatedly. On the pet side, it is easy to give sufficient satisfaction, the texture and the bite are good, the pet is a favorite item, and it is easy to handle. For betting that can fully satisfy various requests such as the possibility of undesired stains such as oil stains on clothes and hands, etc. even when feeding in small pockets etc. Try to provide snack food.

  Based on the above-mentioned problems, the present invention has a main element of the solution means to make a low-nutrition foamed confectionery-like expanded product. Specifically, the following [1] to [6] The gist of the invention is that it has the configuration described in the above.

[1] Contains starch and animal protein as essential components,
A pet snack food characterized by being formed into a highly foamed expanded molded article having an expansion ratio of 3 to 20 times.

  [2] The aforementioned expanded product is formed into a ball shape or a short rod shape having a diameter of 6 to 30 mm by expanding and molding a kneaded product of each material containing starch and animal protein with an extruder. 1] The snack food for pets described in [1].

  [3] The pet snack according to the above item [1] or [2], wherein the starch is a starch composed of one or more materials selected from the group of rice, wheat, corn, potato, sweet potato, and tapioca. hood.

  [4] The pet food according to any one of [1] to [3], wherein the animal protein is composed of one or two materials of livestock meat and fish.

  [5] As optional components, gelatin, sodium lactate, deodorant, tea, salmon cartilage, fermented soymilk, brewer's yeast, various vitamins, and one or more materials selected from the group of okara The snack food for pets according to any one of items [1] to [4], which is additionally contained.

[6] Mixture composition of starch material 30-80% by weight, animal protein material 5-40% by weight, and optional ingredient material 0-40%, water content adjusted to 15-35% Using the mixed composition as a molding material,
By extruding by controlling the extrusion temperature to 100 to 180 ° C. with an extruder having a nozzle diameter of 3.0 to 8.0 mm, it is expanded to a foaming ratio of 3 to 20 times,
A method for producing a snack food for pets, characterized in that, after extruding the extruded material, it is cut to a length of 3.0 to 70.0 mm to obtain a ball-shaped, short-bar-shaped or flat-plate-shaped expanded product.

  The pet snack food according to the present invention as described in the above item [1] includes starch that functions as a binder and animal protein that functions as a flavor, and is molded as a highly expanded foamed product having an expansion ratio of 3 to 20 times. Therefore, the amount of the solid component is extremely small while being bulky. Therefore, even if a large amount is repeatedly given to a pet, there is little risk of excessive intake of nutrients, there is no risk of causing health problems, and the donor can give it with peace of mind, and the pet side also gives a large amount of food. With the illusion that has been made, it can be considered as satisfying.

  In addition, because it is expanded from starch as the main component, it has a relatively strong shape retention despite being a highly foamed expanded product, and it is easy to handle without breaking. It is.

  Moreover, since animal protein is contained and this functions as a flavor, it can be set as the good eating property which pets, such as a dog and a cat, eat.

  Furthermore, since it is molded into a ball shape or a short bar shape as an expanded molded product, the pet does not squeeze without chewing, and it always chews and squeezes, so that the pet has a good texture. Not only that, but also for the donor, the sound of chewing can be heard, so that the donor can feel that the pet is pleasing, and thus more satisfying.

  In addition, as described in the above item [2], when an expanded molded product is expected by expansion molding using an extruder, it contains excessive fat, unlike when it is expanded by oil. Therefore, it is possible to make it easy to handle since it can be often low in nutrients and the surface is not sticky. In addition, since the size and shape of the expanded molded product is a ball or short rod having a diameter of 6 to 30 mm, it is possible to more reliably prevent the pet from being rounded.

  Further, by using the starch material as described in the above item [3], it can be made relatively inexpensive and good in moldability.

  Moreover, by using the animal protein material as described in the above item [4], it is possible to give a pet-like odor and to have good biting properties.

  In addition, by including an optional component as described in the above item [5], the palatability can be improved according to the type of pet, and the health promotion effect of the pet can be achieved. It can be expected.

  Furthermore, by adopting the manufacturing method as described in the above item [6], a suitable pet snack food having various effects as described above can be easily and stably mass-produced with a relatively small number of man-hours. As a result, it can be provided at a low price.

  The pet snack food according to the present invention is mainly for dogs, but is also used for cats, ferrets, and various other small animals raised at home. In the following description, the main use for dogs will be described as a specific example.

  First, the pet snack food according to the present invention contains starch and animal protein as essential components, and more preferably contains various additive materials as optional components.

  The specific material of the starch is not particularly limited, but starch based on one or more materials selected from the group of rice, wheat, corn, potato, sweet potato, and tapioca is preferably employed. . By using these starches, the material can be made relatively inexpensive and have good moldability. Of the above-mentioned starches, it is particularly preferable to use white starch or corn starch purified as corn starch as rice starch. In this case, a moderately high hardness and strength are imparted to a snack food which is an expanded molded product having a high expansion ratio. There are advantages you can do.

  Animal protein mainly functions as a flavor for improving the bite of pets, and is composed of one or two materials of livestock meat and fish.

  More specifically, as for livestock meat, it is preferable to use chicken breast, chicken head, and beef. As the fish, any fish can be used. Examples include salmon, horse mackerel, saury, tuna, salmon, salmon, salmon, yellowtail, flounder, puffer fish, eel, sea cucumber, salmon, salmon, squid, octopus, and the like, although not particularly limited thereto. Among these, it is preferable to use cocoons. In this case, there is an advantage that the palatability of animals such as dogs is further improved, and the biting properties of these animals are further improved.

  Moreover, about these fish, all the site | parts can be used. Specifically, body, head, bones, peeled, fins, other fish processing residue, etc. may be mentioned, one of these may be used, or multiple types may be used in combination, Alternatively, the whole fish may be used. Among them, it is preferable to use at least one of the processing residue of the head, bones, peeled and other fish. These are non-eating parts that remain after fish processing and are usually disposed of, but by using these, it is possible to effectively use waste after fish processing and contribute to the reduction of waste. On the other hand, since these can be obtained at low cost, there is an advantage that the cost can be greatly reduced.

  In addition to the above essential components, the following optional ingredients are added to the snack food according to the present invention as needed.

  That is, gelatin as a thickener, sodium lactate as an anti-aging and pH adjuster, deodorant to prevent bad breath, tea as a calorie reducing agent, salmon cartilage for improving palatability, for health promotion Fermented soybean flour (soybean isoflavone), yeasts represented by brewer's yeast, various vitamins, and okara as an extender.

  The preferred composition of the pet snack food of the present invention using various materials as described above is 30 to 80% by weight of starch material and 5 to 40% by weight in an inherent moisture content of about 70% of animal protein material. In addition, the other optional component material is a mixed composition in the range of 0 to 40% by weight, and the snack food is a mixed composition in which the moisture content is adjusted to 15 to 35% by weight with respect to the mixed composition It has been formed from the expansion.

  And the moisture content in an expanded molding is a thing of the dry state of about 5 to 20%.

  When the content ratio of the starch material is too small, such as less than 30% by weight, the expansion molding becomes difficult. Moreover, even if it can shape | mold, an expansion molding becomes a weak thing, and it becomes a thing which is easy to break and difficult to handle. On the contrary, when the starch content exceeds 40% and the pet biteness tends to be inferior, it is not preferable. A preferable starch blending amount is about 50 to 65% by weight.

  The mixing ratio of the animal protein material is 5 to 40% by weight in a predetermined water-containing state as described above. If it is less than 5% by weight, the flavor effect is insufficient and the pet bite tends to be inferior. On the other hand, when it is excessively blended in excess of 40% by weight, it is not preferable in view of the health of the pet because it becomes a nutrient-rich food and is provided as a snack food.

  The blending amount of other optional components varies depending on the type of additive, but is set within a range of 0 to 40% by weight as a whole. When it exceeds 40% by weight, it becomes inferior in moldability and inferior in pet biting property, which is not preferable.

  The pet snack food according to the present invention using the above blended composition is preferably formed into a ball-shaped or short rod-shaped expanded product by expanding the above mixed composition with an extruder.

  FIG. 1 shows an example of a snack hood (1) formed into a ball shape, and FIG. 2 shows an example of a snack hood (2) formed into a short bar shape.

  These snack foods (1) and (2) are all foamed from the above mixed composition at a foaming ratio of 3 to 20 times. If the expansion ratio is less than 3 times, the volume ratio is excessively nutritious, and it lacks suitability as a snack food including the texture. On the other hand, when it is made to be highly foamed exceeding 20 times, it becomes brittle and easily broken and inconvenient to handle. The preferred expansion ratio is generally in the range of 8 to 20 times, and most preferably about 10 to 15 times.

  The control of the expansion ratio is mainly governed by the water content of the mixed composition and the extrusion temperature. For this reason, the water content is adjusted to 15 to 35%, preferably about 20 to 30%.

  Moreover, it is preferable that all the said snack food (1) (2) is formed in the range of 6-30 mm in the diameter (R). In the case of a short rod-shaped molded product, the length (L) is preferably about 40 to 80 mm. If the diameter (R) is too small, the risk of rounding the hood increases for pets, especially dogs. Moreover, when the diameter (R) including the length (L) is too large, it becomes inconvenient to handle, and it becomes difficult to perform feeding work given to the pet one by one or two to three by hand. There is a fear. The most preferable size is in the form of a ball and is generally about 10 to 25 mm in diameter, more preferably about 15 to 20 mm.

  The method of forming the expanded molding as the snack food of the present invention is not necessarily limited to the expansion molding using an extruder. For example, a thin rod-like extrudate is cut into a predetermined length, and then subjected to a firing process or a frying process. It is good also as what is made to foam and swell by.

  However, as described above, the most convenient and easy production method with good productivity is most advantageous by expansion molding using an extruder.

  That is, it is a mixed composition of starch material 30 to 80% by weight, animal protein material 5 to 40% by weight, and optional ingredient material 0 to 40%, and the water content is adjusted to 15 to 35%. The composition is used as a molding material and is extruded with an extruder having a nozzle diameter of 3.0 to 8.0 mm while being controlled at an extrusion temperature of 100 to 180 ° C., and expanded to a foaming ratio of 3 to 20 times. It is most advantageous to employ a production method in which after the material is extruded, it is cut into a length of 3.0 to 70.0 mm to obtain a ball-shaped or short rod-shaped expanded molded product.

  In the extrusion molding process using the extruder, the set temperature (temperature in the container) of the extruder itself is not particularly limited. It can be set to any temperature in the range of approximately 30 to 250 ° C. Even if this set temperature is low, it is possible to perform expansion molding simultaneously with extrusion by adjusting the rotational speed of the screw during heating and kneading and the moisture content of the kneaded product. However, it is desirable to control the material temperature when extruded from the extrusion nozzle, that is, the extrusion temperature, within a range of 100 to 180 ° C. When this extrusion temperature is too low, such as less than 100 ° C., foaming of the molded product tends to be insufficient. Conversely, when the extrusion temperature exceeds 180 ° C and is too high, the component materials may be altered, and the foam expansion rate of the molding material immediately after extrusion becomes too fast, resulting in a ruptured state and good stable shape. It may be difficult to obtain a simple expanded product. A preferable extrusion temperature is approximately in the range of about 120 to 150 ° C.

  If the diameter of the extrusion nozzle is less than 3.0 mm, the diameter of the expanded molded product is insufficient, and the diameter of the expanded molded product is too large. It will be a thing. A preferable nozzle shape is about plus or minus 1 mm, that is, about 4.0 to 6.0 mm around 5.0 mm.

  The extruded material is cut into suitable dimensions immediately after extrusion from the extrusion nozzle. This cutting is performed by repeatedly involving a shearing blade provided on the outer surface side of the outlet of the extrusion nozzle by rotating or reciprocating driving, and determines the length and thus the shape of the expanded molding as a snack hood. That is, when the extruded material is cut with a length substantially the same as the nozzle diameter, a substantially spherical expanded product can be obtained, and when cut with a dimension longer than the nozzle diameter, the length is longer than the diameter. A substantially short columnar expanded product can be obtained.

  In the present invention, the nozzle diameter of 3.0 to 8.0 mm is not necessarily limited to the case where the nozzle opening is circular, but the equivalent diameter (4 X cross-sectional area / perimeter) to be understood. Therefore, the extrusion nozzle according to the application of the present invention is not necessarily limited to the one having a circular extrusion port.

  Next, specific examples of the present invention will be described.

[Example 1]
As shown in Table 1 below, a mixed composition having a composition of 60% by weight of rice flour as a starch material, 33% by weight of chicken breast as animal protein, 2.0% by weight of sodium lactate, and 5% by weight of brewer's yeast The products were sequentially put into an extruder extrusion container in a state adjusted to a moisture content of 25%, and kneaded sufficiently. The extruder set temperature is set to 120 ° C, the extrusion nozzle diameter is 5.0 mm (circular), the extrusion temperature (discharge temperature) is 150 ° C, the extrusion speed is about 100 mm / sec, and the cut length immediately after extrusion is set to 5.0 mm. Extrusion expansion molding was performed under the conditions. As a result, as shown in Table 3, a slightly yellowish ivory-colored expanded product having a substantially ball shape with a diameter (R) of 17 to 21 mm and an expansion ratio of about 10 was obtained.

[Examples 2 to 8]
Extrusion expansion was carried out in the same manner as in Example 1 except that the composition of the molding material was as shown in Tables 1 and 2 and the extrusion temperature (discharge temperature) by the extruder was set at the same temperature as shown in Tables 1 and 2. Molding was performed. The diameter, shape, expansion ratio, and the like of the expanded molding obtained as a result were as shown in Table 3.

  Next, various expanded articles (pet foods for pets) obtained in Examples 1 to 8 above were evaluated for three items of formability, properties, and palatability, and the results are also shown in Table 3.

[Evaluation of formability]
Those that were able to smoothly perform extrusion expansion molding using an extruder without any hindrance were shown as ◯.

[Evaluation of properties]
The expanded product does not easily lose its shape, has an appropriate hardness and shape retention that does not break with a slight external force, and has no stickiness on the surface, it is considered good in the overall evaluation in terms of properties, Shown with a circle.

[Preference evaluation]
The owner conducts the above for a 3-year-old crossbreed dog and an 8-year-old Shiba dog at the time of 3-4 pm, approximately 2-3 hours before the regular feeding time around 6 pm An experiment was repeated in which each of the expanded moldings of Examples 1 to 8 was given by hand to the nose of the dog. In any dog, if you bite immediately, bite and crush and then bite, evaluate that both bite and texture are extremely good, and mark ◎ For dogs with no bite, or when the biting sound was not clearly heard, a circle mark was given as a bite / feel slightly good.

  As can be seen from the results of Table 3, the snack food for pets according to the present invention is excellent in moldability, properties, and palatability, and is a highly foamed expanded molded product that is extremely substantial if it is bulky. Because the amount is small, even if it is given in a fairly large amount by way of snacking, it does not adversely affect the health of the pet, and as a snack food used to enhance and deepen contact with the pet In applications, it has superior suitability over conventional products.

  The snack food according to the present invention is particularly suitable for cats other than dogs, ferrets, and other small animals to be raised in the home by selecting the type of animal protein material and the type of optional ingredients. It can also be provided as a snack food.

It is a perspective view which shows an example of the shaping | molding state of the snack food for pets concerning the Example of this invention. It is a perspective view which shows the other example of the shaping | molding state of the snack food for pets concerning the Example of this invention.
